Building Braking Devices TRIZ Cases

A self-adjusting stop buffer uses a cam mechanism to raise and lock the buffer head within a central body for precise positioning.

A rotating latch fixed to a notched belt uses motor play to block sliding panels, eliminating fragile electrical contactors and reducing mechanical wear.

A deformable hollow body absorbs thermal expansion of hydraulic fluid, preventing leakage and component failure under high pressure.

Pre-configured post design establishes fixed geometric parameters to eliminate unpredictable speed variations during automatic operation.

Segmenting the cavity into a removable drawer resolves the trade-off between increased storage capacity and handling ease in camera support boxes.

A tilting element rotates upward via magnetic interaction to block a moving object.

Rotating housing spring aligns force with sash motion to reduce locking fitting wear.

Spring carriage anchors coil springs to window frame jambs, supporting side load sashes while eliminating complex block and tackle mechanisms.

A door lock housing incorporates a protruding element to provide structural rigidity and mounting surfaces.

A pump handle mechanism converts linear reciprocating motion into rotational movement of a main shaft to operate building vents.

An intermediary shaft and slide with an inclined plane transmit impact energy to a damper, preventing direct contact that causes premature wear.

A pivoting access door assembly with aligned bevelled surfaces transitions between open and closed states to integrate seamlessly into floor structures.

Dual piston sets and an eccentric cam control door speed, preventing uncontrolled movement between 90 and 75 degrees.

An integrated connecting member with an arcuate slot reduces hinge volume and assembly complexity while preventing component interference.

Eliminating complex cage structures reduces friction losses while maintaining reliable drive power transmission.

Spring-mounted dampers compensate for structural deflections, maintaining reliable movement control under heavy loads.

A sliding door locking apparatus merges hold-open and glass safety functions into a single integrated mechanism.

A crystalline polyamide resin composition enhances sliding durability through modified polyolefin and carbon fiber reinforcement.

A sash lock uses a delay cam to drive a locking cam through distinct rotation phases.

A telescoping diagonal member and sensor detect obstructions, enabling movable partitions to adapt to non-parallel surfaces.

A stepped bore supports an adjusting screw in the cover, enabling external spring tension adjustment despite narrow mounting hole patterns.

Perpendicular control members engage anchors and docking collars to prevent environmental element transfer through sliding panel gaps.

A hinge mechanism with a main spring and damper assembly balances weight to enable automatic, slow, and noise-free oven door closing.

A car door opening mechanism uses nested coupling members to constrain the door at a non-fully opened position during initial swing.

Variable braking force on the check arm prevents unintended door swings and collisions while enabling user-selectable holding positions.
